摘　　要：[目的]探讨海-气界面二氧化碳通量。[方法]采用模型估算法,利用实验室模拟条件来培养贻贝进行计算,并且使用SMARTCHEM仪器监测出碱度后换算出样品中二氧化碳浓度,酸碱滴定法计算出空气中二氧化碳浓度,从而求得气体交换通量。[结果]贻贝数量增加二氧化碳交换通量越多;培养时间越久,二氧化碳交换通量越多。[结论]该研究为渔业碳汇提供科学依据和技术储备。[Objective] The research aimed to explore the carbon dioxide flux at the sea-air interface.[Method]Using the model estimation method, the laboratory simulation conditions were used to culture the mussels for calculation, and the concentration of carbon dioxide in the sample was calculated by using the SMARTCHEM instrument to monitor the alkalinity, and the carbon dioxide concentration in the air was calculated by the acid-base titration method to obtain the gas exchange flux.[Result]The number of mussels increased, and the carbon dioxide exchange flux increased. The longer the culture time, the more carbon dioxide exchange flux.[Conclusion]The study provides scientific evidence and technical reserves for fishery carbon sinks.
